We evaluated the field efficacy of coumatetralyl maize grain bait (0.0375%) against wild boar population in Fatima Jinnah Park, Islamabad.
(Dobson, 1973; Saunders, 1988; O' Brien et al., 1988; McIlroy et al., 1989) Therefore, this study was conducted to determine the effectiveness of an anticoagulant coumatetralyl (manufactured by Bayer, Germany) against wild boar which could supplement or replace the use of 1080 for wild boar control in the longer term.
Coumatetralyl (Racumin) bait was prepared by mixing molasses with whole maize grain, and racumin master mix (0.75%) in the ratio of 1:18:1 by weight, to give a final concentration of 0.0375% coumatetralyl.
Also the development of a strong physiological resistance to
coumatetralyl under antagonistic K vitamin exposure in rodents which may be related to metabolic enzymes [30].
In 2010, rodenticidal effect of Coumavec[R] (a mixture of Coumatetralyl 0.5% and Etofenprox 0.5%) against R.
Along this survey, in another area Coumavec[R] (a mixture of Coumatetralyl 0.5% and Etofenprox 0.5%) was evaluated for ZCL reservoir control and the results were compared with zinc phosphide.
Another method would use anticoagulants such as Warfarin,
coumatetralyl and chlorophacinone, all of them producing a reaction in the rodents' blood system by clotting the blood when vessels were broken; thus, the rats would die of haemorrhages at the slighest scratches.
Field evaluation of
coumatetralyl bait against Indian crested porcupine, Hystrix indica Kerr.
Formulated baits of zinc phosphide (2%) wax cake and broken rice; brodifacoum (0.005%) wax block and coumatetralyl (0.0375%) broken rice were subjected to evaluation.
The tested ready-to-use baits were of zinc phosphide (2%) wax cake., zinc phosphide (2%) broken rice grain in polythene sachet., brodifacoum (0.005%) wax blocks, and coumatetralyl (0.0375%) broken rice grain in polythene sachet.
Groundnut-maize grain bait was tested for its effectiveness in delivering the lethal quantities of coumatetralyl for controlling Indian crested porcupine.
Key words: Indian crested porcupine, Hystrix indica, coumatetralyl, grain baits, groundnut, maize; saccharin.
